Cov hlau nplaum tuaj yeem khaws kub

Koj puas tau xav tias yog hlau nplaum tuaj yeem khaws kub? Ntau tus neeg xav tias vim tias kub yog hlau, nws yuav tsum lo rau cov hlau nplaum, tab sis qhov ntawd tsis yog li ntawd. Kub yog ib txwm tsis yog- sib nqus, uas txhais tau tias txawm tias cov hlau nplaum muaj zog, suav nrog cov hlau nplaum Neodymium, yuav tsis rub nws mus rau lawv. Kev nkag siab qhov no yuav pab koj kom tsis txhob muaj qhov yuam kev thaum kuaj kub lossis sib cais cov hlau. Hauv tsab xov xwm no, koj yuav kawm vim li cas kub coj li no, cov hlau nplaum sib txawv ua haujlwm li cas, thiab cov txheej txheem twg koj tuaj yeem siv los ntsuas lossis tswj kub kom zoo.

Thaum koj tuav lub hlau nplaum ze ntawm kub, tej zaum koj yuav xav kom nws txav los yog lo, tab sis nws yuav tsis. Kub yog diamagnetic, uas txhais tau tias nws yeej tiv thaiv magnetic teb es tsis txhob raug attracted rau lawv. Cov cuab yeej no muaj tseeb rau cov kub ntshiab, txawm tias nws yog npib, bar, lossis cov hniav nyiaj hniav kub.

Koj yuav tsum paub tias tsis yog txhua yam khoom kub coj ib yam nkaus. Qee cov hniav nyiaj hniav kub los yog npib muaj lwm cov hlau xws li npib tsib xee lossis tooj liab, uas tuaj yeem hnov mob me ntsis rau cov hlau nplaum muaj zog. Tab sis txawm li ntawd los, kub nws tus kheej tsis yog hlau nplaum. Kev nkag siab qhov no yuav pab koj cais cov dab neeg los ntawm qhov tseeb thiab tsis txhob cia siab rau cov hlau nplaum los ntsuas kub tiag tiag.

To taub yog vim li cas kub tsis lo rauhlau nplaumpib nrog paub tias cov hlau nplaum ua haujlwm li cas. Cov hlau nplaum tsim ib qho chaw sib nqus, uas yog lub zog tsis pom uas tuaj yeem nyiam qee yam hlau. Tsis yog txhua yam hlau teb tib yam, yog li kev kawm cov hauv paus ntsiab lus tuaj yeem pab koj nkag siab tias vim li cas kub coj txawv txawv.

Cov hlau nplaum nyiam cov hlau uas muaj hlau, npib tsib xee, lossis cobalt. Cov hlau no muaj cov cheeb tsam me me hu ua magnetic domains uas txuas nrog lub magnetic teb, rub cov khoom mus rau cov hlau nplaum. Cov hlau zoo li kub, nyiaj, thiab tooj liab tsis muaj cov npe no, yog li lawv tsis nyiam. Paub qhov no yuav pab koj pom tias yog vim li cas cov hlau nplaum tuaj yeem cais cov hlau tab sis tsis tuaj yeem tuav cov kub dawb huv.

Qee cov hlau nplaum muaj zog ntau dua li qhov koj pom ntawm koj lub fridge.Neodymium hlau nplaumyog ib qho piv txwv nrov; lawv me me tab sis muaj zog heev. Txawm hais tias lawv tuaj yeem khaws cov khoom hnyav hlau lossis hlau yooj yim, lawv tseem yuav tsis nyiam kub. Siv cov hlau nplaum muaj zog zoo li no tuaj yeem pab tshem tawm cov khoom sib nqus ntawm cov kub lossis lwm yam hlau, tab sis nws yuav tsis qhia koj tias koj cov kub yog tiag tiag.

Kev nkag siab txog cov hlau twg yog cov hlau nplaum yog qhov tseem ceeb yog tias koj xav cais cov hlau, sim lawv, lossis tsuas yog paub vim li cas qee qhov lo rau hlau nplaum thiab lwm tus tsis ua. Hauv qab no yog cov ncauj lus kom ntxaws sib piv ntawm cov hlau nplaum sib nqus thiab tsis yog- hlau nplaum, suav nrog kub.

Thaum kub nws tus kheej tsis yog{0}} sib nqus, cov hlau nplaum muaj zog zoo li Neodymium hlau nplaum tseem tuaj yeem pab tau zoo thaum ua haujlwm nrog kub lossis lwm yam hlau. Kev nkag siab txog vim li cas cov hlau nplaum no tshwj xeeb thiab lawv siv li cas tuaj yeem pab koj tuav cov hlau zoo dua.

Neodymium hlau nplaum muaj zog ntau dua li cov hlau nplaum zoo tib yam. Txawm tias cov khoom me me tuaj yeem tsim lub zog sib nqus muaj zog txaus los khaws cov hlau hnyav, npib tsib xee, lossis cobalt khoom. Lub zog no ua rau lawv nrov hauv cov ntawv thov kev lag luam, hluav taws xob, thiab kev sim kev tshawb fawb. Txawm li cas los xij, txawm tias lawv lub hwj chim, Neodymium hlau nplaum tsis tuaj yeem nyiam cov kub ntshiab, vim tias kub tsis muaj qhov sib nqus los teb rau thaj chaw.

Neodymium Magnets

Txawm hais tias kub nws tus kheej tsis yog hlau nplaum, Neodymium hlau nplaum tuaj yeem siv los tshem tawm cov khoom sib nqus los ntawm kub -cov ntaub ntawv. Piv txwv li, nyob rau hauv kub mining los yog panning, cov hlau nplaum no pab cais cov hlau los yog lwm yam hlau nplaum los ntawm cov xuab zeb thiab pob zeb. Qhov no tso cai rau koj kom tau txais cov qauv huv ntawm cov kub yam tsis muaj kev cuam tshuam cov kub nws tus kheej. Los ntawm kev siv cov hlau nplaum muaj zog, koj tuaj yeem txhim kho kev ua haujlwm ntawm cov hlau sib cais thaum txo kev puas tsuaj rau cov hlau muaj txiaj ntsig.

Thaum cov hlau nplaum tsis tuaj yeem nyiam cov kub ntshiab, lawv tseem tuaj yeem muaj txiaj ntsig zoo hauv qee qhov kub - sim cov xwm txheej. Kev siv lawv kom raug tuaj yeem txuag koj lub sijhawm thiab pab koj cais cov hlau zoo.

Cov hlau nplaum feem ntau yog siv los ua kom pom cov hlau sib xyaw nrog kub uas tuaj yeem cuam tshuam nrog kev sim. Piv txwv li, yog tias tus qauv kub muaj cov hlau nplaum zoo li hlau lossis npib tsib xee, cov hlau nplaum yuav rub tawm. Qhov no tso cai rau koj cais cov khoom tsis yog- sib nqus, ua kom yooj yim rau kev tshuaj xyuas lossis ua cov kub ntxiv.

Hauv kev mining lossis hlau rov qab, cov hlau nplaum pab tshem tawm cov khib nyiab sib nqus los ntawm kub- muaj cov xuab zeb, pob zeb, lossis cov pob zeb crushed. Cov kauj ruam no tsis txheeb xyuas seb cov kub puas yog tiag tiag, tab sis nws txo qis kev sib tsoo thiab tiv thaiv cov kev xav tsis tseeb thaum kuaj pom.

Los ntawm kev tshem tawm cov impurities sib nqus nrog cov hlau nplaum ua ntej, koj xyuas kom meej tias lwm yam kev sim, xws li kev ntsuas kua qaub, kuaj xyuas qhov ntom ntom, lossis cov ntsuas hluav taws xob kub, yog qhov tseeb dua. Txoj hauv kev no cia koj tsom mus rau kub nws tus kheej yam tsis muaj kev cuam tshuam los ntawm cov hlau nplaum hauv cov qauv.

Txawm hais tias cov hlau nplaum tuaj yeem pab tshem tawm cov hlau nplaum tsis huv, lawv tsis tuaj yeem paub meej tias qhov kub yog qhov tseeb. Hmoov zoo, muaj lwm txoj hauv kev txhim khu kev qha muaj los ntsuas kub kom raug.

Cov khoom siv hluav taws xob kub yog cov khoom siv tes tuav uas tuaj yeem ntsuas cov hluav taws xob conductivity ntawm kub los txiav txim siab nws cov purity. XRF (X-ray fluorescence) tsom xam yog lwm qhov siab - txoj kev ua kom paub tseeb uas txheeb xyuas qhov tseeb ntawm cov hlau tsis muaj kev puas tsuaj rau cov khoom. Cov cuab yeej no tso cai rau koj los txheeb xyuas cov ntsiab lus kub sai sai, ua rau lawv ntseeg tau ntau dua li kev cia siab rau cov hlau nplaum.

Kub muaj qhov ceev tshwj xeeb ntawm 19.3 g / cm³, uas yog ntau dua li lwm cov hlau. Koj tuaj yeem sim ib daim kub los ntawm kev ntsuas nws qhov hnyav thiab ntim los xam qhov ceev. Yog tias qhov ntom ntom sib xws nrog kub tus qauv, nws yuav yog qhov tseeb. Txoj kev no yooj yim, tsis yog - puas tsuaj, thiab siv tau rau npib, tuav, thiab cov hniav nyiaj hniav kub me me.

Yog tias koj tseem siv cov hlau nplaum kom tshem tawm cov hlau nplaum tsis huv, ua tib zoo tuav lawv. Cov hlau nplaum muaj zog zoo li Neodymium hlau nplaum tuaj yeem rub koj cov ntiv tes lossis ua rau cov khoom siv hluav taws xob puas tsuaj nyob ze. Khaws cov hlau nplaum kom deb ntawm cov khoom rhiab, thiab yuav tsum hnav hnab looj tes yog tias xav tau. Los ntawm kev ua raws li cov kev ceev faj no, koj tuaj yeem ntxuav koj cov qauv kub kom nyab xeeb thaum tiv thaiv koj tus kheej thiab koj cov hlau muaj txiaj ntsig.

Neodymium magnets

Kub tsis yog -magnetic xwm txheej nws sib nrug los ntawm cov hlau feem ntau, ua rau nws yooj yim cais los ntawm cov khoom sib nqus thaum xav tau. Thaum cov hlau nplaum muaj zog, xws li cov hlau nplaum Neodymium, tuaj yeem pab tshem tawm cov khoom tsis huv lossis huv huv -cov qauv, lawv tsis tuaj yeem lees paub qhov tseeb ntawm kub. Txhawm rau kom ntseeg tau qhov tseeb, cia siab rau cov txheej txheem pov thawj xws li cov ntsuas hluav taws xob kub, XRF tsom xam, lossis ntsuas qhov ceev. Kev nkag siab txog tus cwj pwm ntawm cov kub thiab lwm yam hlau tsis yog tsuas yog pab koj kom tsis txhob muaj kev xav tsis zoo xwb tab sis kuj tso cai rau koj los tswj kub kom zoo thiab ua haujlwm zoo. Los ntawm kev tsom mus rau kev paub thiab cov tswv yim tsim nyog, koj tuaj yeem txiav txim siab zoo dua txawm tias koj tab tom sim, mining, lossis ua haujlwm nrog kub hauv txhua daim ntawv.
